Description
Technical field
The invention belongs to fire extinguisher bomb technical fields, and in particular to a kind of airborne fire extinguisher bomb.
Background technology
In fire-fighting domain, high level fire extinguishing is always a world-famous puzzle, and the fire risk of skyscraper and fire extinguishing are difficult
Degree is far longer than general low-rise building.When on fire for general skyscraper, traditional extinguishing method is to allow disappear by fire-fighting rack
Anti- member climb to tens meters height locate, fireman recycle hydraulic giant to ignition point implement put out a fire, it is clear that this method efficiency with
Fire extinguishing height limitation is short of and had in safety, once fire extinguishing height is just helpless beyond a certain range conventional method
, and air attack robot has congenital sexual clorminance in high level fire extinguishing, but although various air attack podium levels go out not
Thoroughly, but the slightly aobvious lag of the development of airborne fire-extinguishing apparatus, the corresponding high performance Airborne Fire Fighting Equipment of development could really play sky
Advantage of the middle firefighting robot in high-rise fire extinguishing.
Application No. is propose a kind of fire extinguisher bomb in the innovation and creation of 201410710362.X.The fire extinguisher bomb uses high pressure gas
Body propulsion device is more heavy, and the general lifting capacity of aerial platform is limited, and the fire at one that goes out needs repeatedly round-trip, this can be dropped significantly
Low fire-fighting efficiency needs constantly to carry out gas filling when the bullet uses in addition, is unsuitable for fire-fighting scene.
It is a kind of based on the fire extinguisher bomb for shedding pattern in the air application No. is being proposed in the innovation and creation of 201610930267.X.
The innovation and creation emphasis elaborates to hang fire after fire extinguisher bomb breaks window and shed the theory of extinguishing chemical, is not directed to pushing away for fire extinguisher bomb
Into, the carry etc. of broken window and aerial platform, more stress the narration for the pattern of shedding.
Application No. is propose a kind of fire extinguisher bomb in the innovation and creation of 201610990378.X.The fire extinguisher bomb is by gunpowder explosion
Extinguishing chemical is pushed to catch fire by the thrust of generation sentences extinguishing burning things which may cause a fire disaster, and bullet inherently has spot fire hidden danger using gunpowder explosion；
Although this fire extinguisher bomb can be thrown by aerial platform carry, there is no broken window abilities, generally have tempered glass guarantor with practical high level
The reality of shield is not inconsistent, and limits its application in high level fire extinguishing.
Application No. is the fire extinguisher bombs that fire-fighting is proposed in 200420009379.4 innovation and creation.The fire extinguisher bomb is also by exploding
The thrust of generation pushes extinguishing chemical to the place that catches fire, and leads to potential fire hidden danger, fire-fighting efficiency is not high, is penetrated using the machine of firing
Go out, fire-fighting efficiency and precision are difficult to ensure.

Compared with prior art, the present invention, which carries, has the following advantages：
One, can be achieved aerial platform carry and transmitting, not by fire extinguishing height limitation.
Conventional fire extinguisher bomb is generally carried along into the scene of a fire by fire fighter and puts out a fire or taken aim at from bottom of the building by ground launch vehicle
Quasi- transmitting, the mode that fire fighter carries are limited to fire fighter and can not on a large scale and largely use, and car launcher transmitting then by
The angle of departure for being limited to car launcher is not used to too high floor.The fire extinguisher bomb of the present invention can be flown by aerial platform carry to catching fire
High building is put out a fire, and eliminates the limitation of fire extinguishing height, and in view of high level generally has tempered glass protection, fire extinguisher bomb of the invention
Window cone is also specially devised brokenly, realistic situation is more in line with.
Two, light weight, extinguishing chemical loading mass is big, sphere of action is big.
The material that structure of the invention uses is light material, and fire extinguisher bomb uses dry powder fire extinguishing agent, and density is small, quality
Gently, therefore body structure can load more extinguishing chemicals.Since air attack platform lifting capacity and cruise duration are limited, fire extinguishing
Playing light weight means that greater number of fire extinguisher bomb can be loaded with aerial platform, and extinguishing chemical loading mass means greatly Dan Mei
The sphere of action and effect of fire extinguisher bomb fire extinguishing are more preferable, these are most important to improving fire-fighting efficiency.
Three, using quick and easy.
The fire extinguisher bomb of the present invention is disposable, is not necessarily to other extra preparations, is used cooperatively, has emitted with mating guide rail
Transmitting operation next time can be carried out on platform in the air by carry fire extinguisher bomb again after finishing, time is short, easy to operate.
Four, flying speed is fast, and rate of descent is small.
The engine average thrust of fire extinguisher bomb proposed by the present invention is 500N, and peak acceleration reaches 166.7m/s2, flight
Maximum speed can ensure that it has good air force up to 50m/s, fire extinguisher bomb body configuration design of the invention in the process
Performance and ballistic characteristics, aerodynamic drag is small in flight course, and flying speed is fast, and flight stability is high, while the design of empennage makes
The rate of descent of fire extinguisher bomb body in certain distance flight course is small.
